Individuals in Hong Kong, diagnosed with lung cancer, encouraged to undergo testing, following actor Will Or's revelation of his illness
In Hong Kong, the recommended method for early detection of lung adenocarcinoma in high-risk individuals is through low-dose computed tomography (LDCT) screening. This approach is particularly enhanced by artificial intelligence (AI) assistance, making it more efficient and affordable [1].
The effectiveness of LDCT screening has been demonstrated, notably in detecting lung cancer at earlier stages among high-risk groups, including non-smokers with a family history of the disease. AI integration helps improve the interpretation of LDCT scans and potentially reduces costs by nearly half compared to traditional methods [1].
Risk prediction models validated in Chinese populations, such as those assessed in studies involving cohorts like the Guangzhou Biobank, can guide the identification of high-risk individuals more accurately than simple clinical criteria. This targeted approach can improve screening outcomes by focusing LDCT on those with the highest probability of developing lung cancer [2].
Emerging research is exploring the combination of LDCT with biomarker-based tests, such as multiple tumor-related autoantibody assays, which may enhance the specificity and sensitivity of screening [3].
These developments align with global lung cancer screening guidelines, adapted to local epidemiology and resource settings in Hong Kong [1][2][3]. It's important to note that lung adenocarcinoma is a common form of cancer, making up 16.1% of new cases in 2022 [4].
Recent events have sparked a renewed call for early cancer screenings among residents at higher risk. Actor Will Or Wai-lam's diagnosis of stage-four lung adenocarcinoma has raised concerns about this type of cancer. Medical experts have warned that lung adenocarcinoma is often discovered at late stages [5].
In response to these concerns, doctors are urging residents at higher risk to receive screenings with LDCT scans. The screenings aim to catch lung adenocarcinoma early on, potentially improving the chances of successful treatment. Or Wai-lam's diagnosis has forced him to withdraw from his first theatre production [6].
The public's concern over lung adenocarcinoma following Or Wai-lam's diagnosis has led to the implementation of these screenings. Respiratory medicine specialist Dr Leung Chi-chiu emphasised the importance of early detection, stating, "Lung cancer is the most common cancer in Hong Kong, and early detection can significantly improve the chances of successful treatment" [7].
Some people, including those working, may find lung adenocarcinoma in earlier stages during routine body checks. The screenings are a proactive measure to ensure that more cases are detected early, improving the overall prognosis for those affected.
- To combat late-stage lung adenocarcinoma diagnoses, such as the one experienced by actor Will Or Wai-lam, health officials are advocating for increased use of low-dose computed tomography (LDCT) screenings, which, when combined with emerging technologies like artificial intelligence (AI), could potentially enhance both the efficiency and affordability of lung cancer detection [1, 6].
- Aside from improving early detection in high-risk individuals like non-smokers with a family history of lung adenocarcinoma [2], advancements in AI and risk prediction models like those validated in Chinese populations [2] can also contribute substantially to the accurate identification of those at a higher risk for respiratory medical-conditions, such as lung cancer [1, 2].
- Fitness and exercise are undoubtedly important for overall health and wellness, but preventative measures such as early cancer screenings, like those for lung adenocarcinoma, are equally crucial. Thus, in addition to promoting health and wellness [3, 6], we should also emphasize the importance of regular health check-ups and early detection methods [1, 2, 3, 5, 7].
